QR codes have become an integral part of modern business operations, enabling quick access to information, payments, and authentication processes. However, this convenience comes with a growing risk: quishing, or QR code phishing. As cybercriminals exploit QR codes to deceive unsuspecting victims, businesses must remain vigilant to protect their data and operations.
What is Quishing?
Quishing involves the use of malicious QR codes to steal sensitive information. When scanned, these codes can direct users to fraudulent websites designed to harvest personal data, login credentials, or financial information. The rise in mobile device usage for business activities, coupled with their lack of security measures, has made this form of phishing particularly effective.
How Does Quishing Work?
Cybercriminals embed malicious QR codes in emails, documents, or even physical locations. Once scanned, these codes redirect users to fake websites that mimic legitimate ones. Victims are then prompted to enter sensitive information, which is captured by attackers.
Key Tactics Include:
- Embedding QR codes in phishing emails that appear to be from trusted entities.
- Placing malicious QR codes on physical posters or brochures in public places.
- Exploiting the security vulnerabilities of mobile devices, which are often less protected than corporate networks.

Why Businesses Are at Risk
Businesses, especially those with mobile-first operations, are prime targets for quishing attacks. The shift to remote work and mobile-based transactions has expanded the attack surface for cybercriminals.
Preventative Measures
To mitigate the risk of quishing, businesses should:
- Educate employees about the risks of scanning unknown QR codes.
- Regularly update mobile security protocols and use trusted cybersecurity software.
- Implement multi-factor authentication for sensitive accounts.
- Use QR code scanning tools that verify the destination before opening it.
As QR codes become more embedded in daily business operations, the risk of quishing cannot be ignored. Proactive measures and employee awareness are essential to safeguarding sensitive information from this growing cyberthreat.
